Working quickly, cook the Bisquick™ batter in a skillet or griddle. Each should be roughly the same size, about 7-8 inches across. As soon as the pancake is cooked, spread 2 tablespoons of the frosting on top and continue layering hot pancakes and frosting until you run out of batter.

Spread one final layer of frosting over top. Place cake in fridge and allow to cool and set completely, for about an hour.
